"Rockin' Robin" (originally released as "Rock-In Robin" on the Class Records 45 single) is a song written by Leon René under the pseudonym Jimmie Thomas, and recorded by American singer Bobby Day in 1958.

"Rockin' Robin" is in the public domain, as the owners never renewed the copyright.

It was the biggest hit from the album, hitting number 1 on the Cash Box singles chart and peaking at number two on both the Billboard Hot 100, behind "The First Time Ever I Saw Your Face" by Roberta Flack,[14] and the Billboard soul singles chart, behind "In the Rain" by the Dramatics.

[15] Record World said that "little Michael rocks in with a revival of the big Bobby Day hit of the rockin' 1950s".

In 1999, English singer Lolly released a cover of "Rockin' Robin" as a double A-side single with "Big Boys Don't Cry".
